invalid Dream Skin style preset

Error message

invalid Dream Skin style preset

What it means

Validation guard in validate_theme_draft: style_preset, when provided, must pass valid_theme_id (1-64 chars, starting alphanumeric, only lowercase letters/digits/'-'/'_'). Fires on a preset name that is malformed or not a registered preset identifier; empty string is allowed (means no preset).
